Dear Bill,
You are right on with the egg masses and habitat [message #15294]. Flabellina vansyoci will only feed on those hydroids and the dark pink is their egg mass. And yes, the 3-4 spots where I find F. vansyoci are the only spots where I find the hydroid, however, I have not been able to figure out what is different in those sites that make only them suitable and not others.

The egg mass of Flabellina telja is always pale pink, another difference is that F. vansyoci lays the eggs on the hydroids and F. telja does so on the substrate.

Bajaeolis bertschi, Hermosita hakunamatata, Flabellina marcusorum and Flabellina sp. from Bahia de Banderas also lay dark-rose pink egg masses, though their shapes (the egg masses) and habitats are very distinct.

Kind regards
Ali
